SHOCK-HANDLING APPARATUS.

Specification of Letters Patent.

Patented May 23, 1911.

Application filed March 8, 1910. Serial No. 548,006.

To all whom it may concern:

' Be it known that I, NEWTON W. LYON, a citizen of the United States, residing at Iowa City, in the county of Johnson and State of Iowa, have invented a new and useful Shock-Handling Apparatus, of which the following is a specification.

This invention relates to a shock handling apparatus and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide a simple and efiective means for contracting the base portion of a shock as it stands in vertical position and for tilting the shock into a horizontal position and holding the base portion thereof contracted while a binder is applied thereto.

Thus it consists of means for tilting the shock into a horizontal position or it may be swung over upon its side upon a truck or other vehicle preparatory to transportation.

A further object of the invention is to include in the apparatus means for elevating and moving the shock in order that it may be deposited or stored at any desired point.

With the above object in view the shock handling apparatus includes a suspended track upon which is mounted a carriage having a locking device adapted to engage a keeper provided at one end of said track. A draft cable is operatively mounted with relation to the track and the carriage and is also connected with a frame adapted to be applied to the side of the shock and the said frame and the draft cable together with auxiliary cables form a means for contracting the base of the shock as indicated.

In the accompanying drawings,-Figure 1 is a perspectlve view of the apparatus. Fig. 2 is a side elevation of a shock with the frame applied thereto. Fig. 3 is a plan view of the frame applied to a shock. Fig. 4 is a side elevation of a modified form of frame. Fig. 5 is a top plan view of a portion of the frame showing a serrated cleat applied thereto. Fig. 6 is an elevation of the apparatus showing a modified form of frame applied to the shock which is in upright position. Fig. 7 is an elevation of a portion of the apparatus illustrating the parts in the act of contracting the base of a shock and tilting the same. sectional view of a portion of the carrier of the apparatus. Fig. 9 is a side elevation of Fig. 8 is a the carriage forming a part of the carrier of the apparatus. Fig. 10 is a transverse sectional view through the track and carriage of the carrier. Fig. 11 is a plan View of a portion of the locking mechanism of the carriage.

In the assembla e of parts as illustrated in Figs. 1 and 6 of the drawings, the shock handling apparatus includes a platform 1 upon which is mounted a superstructure or frame 2. A track 3 is suspended from the frame 2 in the usual manner and is located above the platform 1. The platform 1 and the frame 2 may be the structure of a slide, sled or vehicle and one end of the track 3 projects beyond the end of the platform 1 for the purpose of raising the shock clearof the platform. The frame 2 includes an elevated beam 4 which lies transversely under the inner portion of the track 3. A carriage 5 is arranged to move along the track 3 and the said carriage with its component parts together with the said track.

form the carrier of the apparatus.

In the form of shock contracting frame as illustrated in Figs. 2, 3 and 7 of the drawings the said frame includes a bar 6 which is mounted at its end upon legs 7. The end ortions of the said legs which are connected with the bar 6 converge toward each other. A cable 8 is secured at one end to the bar 6 at the point 9 thence passes around a sheave 10 carried by a block 11 and the said block 11 is attached to a cable section 12. From the sheave 10 the cable 8 passes back to the bar 6 and through the same and around a sheave 13 journaled on the outer side thereof. From the sheave 13 the cable 8 passes around a sheave 1 1 also located upon the outer side of the bar 6, then through the said bar and around a sheave 15 journaled in a block 16 which in turn is attached to a cable section 17. The cable sections 12 and 17 are adapted to be adjustably tied together as at 18. From the sheave 15 the cable 8 is passed back to the bar 6 and through the same and around a sheave 19 which is journaled upon the outer side thereof. From the sheave 19 the said cable 8 passes around a sheave 20 also journaled upon the outer side of the bar 6 and is directed toward the periphery of the sheave 20 by means of a guide 21 of usual pattern. At a point between the sheaves 19 and 20 a cable clutch 20 of usual pattern is located upon the bar 6. This clutch is adapted to engage the cable 8 and prevent backward movement of the said cable until the clutch is released.

As illustrated in Fig. 5 of the drawings, the bar 6 is provided upon its inner side with a serrated cleat 22.

From the above description it will be seen that when the cable sections 12 and 17 have been adjusted with relation to each other and tied as at 18 and the bar 6 placed against the side of the shock 23 and the cable 8 is drawn the blocks 11 and 16 are drawn toward the bar 6, the base of the shock 23 is contracted, and when the base of the shock ceases to contract and draft is continued to be applied to the cable 8 the shock 23 may be tilted as indicated in dotted lines in Fig. 7 over upon the platform of a load vehicle 24. During such tilting movement the legs 7 serve as fulcrums for the shock, and thus during the tilting of the shock the stalks thereof are not pushed longitudinally out of proper relation to each other. It is understood that the shock as it stands upon the ground is provided with =the usual binder 25 in the v1c1n1ty of 1118 upper end. Prior to the contraction of the shock at the base a binder 26 may be placed across the apparatus as shown in Figs. 2

and 6 so as to retain the shock in contracted condition after the sections 12 and 17 have been released. After the binder 26 has been applied to the shock 23 and the same has been thrown over upon its side as illustrated in Fig. 1 of the drawings, the shock may be engaged by a hay fork of the 'harpoon type or tongs, as indicated at 27 in Fig. 1 of the drawings. Or any other means may be employed for engaging the shock while in such position.

In the form of tilting frame as illustrated in Fig. 4 of the drawings a supplemental bar 28 is attached to the upper. ends of the legs 7 and the said bar is parallel with the bar 6 and is provided with a sheave 29 around which the cable 8 passes after passing around the sheave 20. This form of tilting frame is desirable when the shocks are wanted to be contracted close to the base and yet be tilted over and upon a low vehicle. In the form of frame as illustrated in Fig. 6, the bar 6 with its pulleys only is employed and the legs 7 are eliminated. This form of the frame is used to lift the shock direct from a normal position to the carrier by making use of the cable 47 explained hereinafter as an extension to the cable 8. After adjusting the cable sections 12 and 17 draw the cable 8 out as far as possible by hand on account of the upward angle of the draft cable 47 as shown in the illustration (see Fig. 6). This preliminary contraction of the shock is retained by the clutch 20. The shock will be further contracted from the weight of the shock on the lifting cable 47 and by said cable raised against a bolt 42 (to be described hereinafter) and thence forward as hereinafter described. The above mentioned frame or device may also be used to contract the shock and tilt it over and upon a hay slide or low. vehicle.

The carriage 5 which forms a component part of the carrier consists of a frame30 to which are journaled wheels 31 which in turn travel upon the upper side of the track 3. The frame 30 is provided at a point below the track-3 with a jaw 32 and an arm 33 is pivoted to the lower portion of the frame 30 and is provided with a jaw 34 which is located below the aw 32. Said arm 33 is connected with an arm extension 33. The jaw 34 is provided at one side with a flange or lug 35 which projects beyond the side of the jaw 32. A shaft 36 is journaled in the jaw 32 and. an eccentric 37 is mounted upon the said shaft 36 and is located above the flange or lug 35 of the jaw 34.

A sector 38 is fixed to the end portion of the shaft 36 and forms a crank whereby the said shaft may be turned upon its axis. A sheave 39 is journaled upon the arm extension 33 and the forward portion of the arm 33 is pointed as at 40 and is provided with a shoulder 41 located behind the pointed extremity 40 thereof. A bolt 42 is'slidably mounted in a perforation provided in the pointed end portion 40 of the arm extension 33 and a guide 43 is located at the lower end of the bolt 42. A keeper 44 is fixed to the under side of the track 3 and is provided with an inclined side 45 which is located in the path of movement of the pointed end 40 of the arm extension 33. A latch 46 is pivotally mounted in the keeper 44 and when the pointed end 40 of the arm extension 33 is in engagement with the inclined side 45 of the keeper 44 the free end of the said latch 46 will lie behind the shoulder 41 of the arm extension 33 and over the upper end of the bolt 42. When the tongs 27 or other similar shock engaging means is employed one end of the cable 47 is secured to the eye 48 upon the frame 30, then passes down and engages the shockengaging device 27 and passes up through the guides 43 and over the wheel 39 and be tween the jaws 32 and 34. The cable then extends along the track 3 and passes around a pulley 49 journaled upon the beam 4 and from thence passes around a pulley 50 supported at the rear portion of the frame 2 and thence around a pulley 51 supported at the lower forward portion of the frame'2 and from the said pulley may be attached to draft animals or a winding drum as desired. Thus it will be seen that as the cable 47 is drawn longitudinally through the jaws 32 and 34 while the forward end of the arm 33 is in engagement with the inclined side 45 of the keeper 44 the shock 23 will be elevated toward the carriage 5. When the said shock or its securing devices come in contact with the plate 43 the bolt 42 is moved vertically and the upper end thereof pushes the free end of the latch 46 from behind the shoulder 41 and the weight of the shock will swing the arm 33 down and the pointed extremity 40 of the said arm will move away from the inclined side 45 of the keeper 44. As the arm extension 33 swings as indicated the jaw 34 moves toward the jaw 32 and the cable 47 is clamped between' the said jaws. As the cable continues to move longitudinally the carriage 5 is drawn along the track 3 toward the rear end of the frame 2. When the carriage has arrived at a desired point along the track 3, an operative pulls the rope 50 which is attached to the sector 38 and thus the said sector is swung, which in turn will partially rotate the shaft 36 which carries the periphery of the eccentric 37 down upon the flange 35 of the jaw 34 and thus the said jaw 34 is moved away from the jaw 32 and the cable 47 is liberated. At the same time the cable 47 is permitted to come to a state of rest and then as the said cable 47 is slackened the shock is lowered in position upon the platform 1.

Having described the invention what I claim as new and desire to secure by Letters Patent is 1.
